Oh, nowadays there are services that make this easy. Maybe I’ll actually do it?
I’ve been thinking I should make a manifest destiny t-shirt. Manifest destiny has a bad rep these days, but I don’t think it deserves it. Besides, nobody would understand the t-shirt. If I put Mercury on the front, people will take it for the Moon (Caloris Basin on Mercury is really distinctive, but that’s nothing compared to the general impression). Pluto/Charon on the back would look like two fuzzy blobs (in the Hubble pictures; other pictures I’ve seen look like one fuzzy blob with a bump on it). That such a simple message is incomprehensible says a lot to me. Space travel could use a self-fulfilling prophecy.
